- t A COUNTERTUR Application filed October p is carried by a swinging arm, and in or or to cause the rear edge of the plunger to clear the top edge of the cup and'yet cause the counter to conform to the desired contour, it has been customary to cut away the lower rear face of the cup to allow room 20, for the upper to bend while the cup is be: ing pushed forward against the plunger during the latter part of its turning move ment. i

This invention provides simple means by 2. which the plunger is given a movement to properly shape the counter without the necessity of moving the cup, and which allows the use of a cup havinga solid underout rear wall. This form of cup cooperating with the plunger produces a wiping and pressing action on the. counter which acts to smooth the latter preventing much of the w vrinkling usually produced by the turning operation. Preferably the movement of the plunger against the rear face made yilding.

While a solid cup may be employed, this invention further contemplates the use, if desired, of a modified form of cup which is composed of two parts one of these parts, comprising the major portion of the cup side faces, being rigidly fixed, while the other part comprising the back face of the cup and the remaining portionsof the side faces. is so mounted as to yield rearwardly under pressure of the shoe and plunger,

thereagainst. With this form of cup, the yielding movement of the plunger may be dispensed with, if desired, or it may he used in addition thereto;

Referring-to Figs. 1 to 4 inc.,,A. repre-. sents the'upper portion of amachine standard carrying a head or frame B for support: ing the turning implements. At itsforward ,end, the head B has aforwardly andupwardly extending bracket 1 having an inclined end 2 and recessed at 3 to receive, the pivot" 4, 'ofa cup carrying-turret 5 As shown, this turret has a plurality, of doye tail slotted cup carrying arms 6 to which cups 7 of various sizes" may be made fast, each cup having a dove-tail mating the. slo

I cross section on line in the arm 6, and being fixed in position by any suitable means such as a screw. clamp, as shown at 7*. The cup? has upstanding side faces 8 and'9, and an undercut rear face lO, andis open on its forward side in the usual manner. "The turret is retained in position on the) bracket 1 by means ofa set screw 11 engaging a'circum ferential groove 12 in the pivot 4. 'It

held in position with any desired cup --in operative positiongby means of a latchbolt provided in theturret 5 for engagement: with the bolt 13 when a form is pr pilfly positioned. A retracting finger 16 projects outwardly from the latch bolt andprovides means for disengaging'the same from the turret. l

portiofijc .d tan e y f rmfin cross; I 119' v nut28, and a spring 29 surrounding the rod wardly' 'At its up per end member C has pivoted thereto, spaced arms and 21 of a link 22 which at its outer end has a slot 23 pin 26 which is threaded at its inner end and screwed into a mating threaded opening in the pivot 24. The outer end of pin 26 1S.

threaded at 27for the reception of a thumb 26 bearsiat one end against the boss and at the other against thenut 28. This spring 29 acts to holdthe pivot 24 yieldingly at its outward limit of motion within the slot 23, the force of its action depending on the adjustment of the nut 28.

, The pivot 24 is fixed between the upper end of flanges 30 and 31 of a bar 32 of U shape cross section. The lower end of bar '32 ;tern inates in a reduced solid portion 33 having a socket 34' for the reception of a shank 35 of a turning implement comprising a plunger 36 which may be made fast in position by a set screw 37. Below the link 22, and arrangedout of parallelism therewith, is a link mechanism comprising a pair-of arms 40 and 41 pivoted at their inner ends at 42 to the side flanges of the brackets C and at their outer ends pivoted between the flanges 30 and 31 of bar 32 by the pin 43. Also pivoted on the. pin 43 and positioned between the members 40 and 41 is an upwardly extending link 44, to the upper end of which is pivoted at 45 the forward end of" a leverarm 46, fulcrumed at 47 between rearwardly extending ears 48 and 48 carried by themember G, the rear wall of this member terminatin therebelow to allow play of the lever 46. etween the pivots 45 and 47, a rod 49fis pivoted at 49 to the lever 46, this rod projecting downwardly through the base of the head B and into the standard A where it may be attached to any suitable means for, depressing it, such as a treadle, not shown. Acoils'pring-5O is made fast at its upper end adjacent the top of the standard A and at its lower. end to a collar 51 adjustably fixed to the. rod 48..

' The operation of this mechanism is as follows i In normal position of the parts spring acting against the rod 49, holds the outer end of lever 46 upwardly and acting through. the link, 44, and the pivot 43 retains the I plunger36 out of thecup and raisedsufiicien'tlythereabove so that the operator may place'the counterofa shoe to be turnedovcr thecup 7 with the rear inner face of the cou-nteryagainst the outer, rear face of the cup. On depressing the rod 49 by meansof the treadle, the plunger .36 is nowbrought down against the heel portion of the shoe a the point ofattachment of the upper to the sole, .Qn further depressing the treadle plunger 36 is forced downwardly within the cup, turning the counter over the side and rear edges thereof, the sole passing down through the open front end. .As the plunger advances within the cup theangular relation of the links 22 and. 40 and 41 causes theplunger'to moverearwardly toward the rear wall or closed end of the cup, thus substantially following its undercut contour and pressing the counter firmly thereagainst and wi in the sides of the counter against the cup side faces. It should be notedthat the link comprising the arms 40 and 4l'is out of parallelism with the link 22, the outer ends of these links being further apart than their inner ends. This arrangement causes the pivot 43 to; move inwardly toward, the bracket C while the pivot 24 is still substantially at its furthestposition therefrom by which action, the required motion of the plunger rearwardly is produced. It should also be noted that the spring 29 allows the upper end of the bar 32 to yield inwardly and thus imparts a yieldingpressure between 1,

into the cup, this action. of the parts molding the counter to itsproper form withoutfnecessitating movement of the cup,

In Figs. 5 to 8, is shown a modified form of the cup which may be used'if desired. With this modification, the arm 6 of the cup supporting turret, is provided with, a dove-tail'slot 60 longitudinally thereof, and

at its outer end is an upstanding lugv 61.

Slidable within the groove 60 is a mating dovetail 62 fixed to or integral with therear portion 63 of the turning cup 7 The,

dove-tail 62 .is cut through vertically for a portion of its length at its forward end for the reception of a depending rib 64 fixed to or integral with a forward section of the cup, this section comprising upstanding portions 65 and 66 at either side which form the major portions of thelateral sides ofthecup',

the latter being open on its forward. in theform heretofore described.

The rear cup portion v63 has forwardly ex tending portions one of 'which is show-nin. Fig. 5 at 67 normallyprojecting over the portions 65 and 66 and completing. the top side portions of the cup... The forward. cup portion is fixed in position, on the arms ;6 by means of a bolt or cap screw 68 passing side as through a perforation in the arm it and having threaded engagement with a perforation in the ribfia. The rear portion of the dove-tail 62 is recessed at 69 and a spring 7 0 bearing at its forward end against the base of this recess and at its rear end against the lug 61 normally urges the rear cup portion forwardly into close contact with the forward cup portion. A pin 71 threaded in the lug 61 enters the 'coils of the spring 70 and serves as a guide there for. When this cup is being used, and the plunger descends therein to turn the shoe, the rear portion of the cup is allowed to yield relative to the sides by the action of the the spring 70 the stationary side members 65 and 66, engaging the counter portions of the shoe on either side, acting as wipers to smooth the upper forwardly from the heel endduring the rearward motion of the plunger and shoe against the rear cup portion. When the plunger is lifted from the cup, the rear portion thereof moves forwardly through the action of the spring 70 into its former closed position.

Having thus described certain embodiments of this invention, though it is evident that many changes and modifications might be made therein without departing from its spirit or scope, what is claimed is:
